New Delhi: The Reserve Bank of India (RBI) is planning to introduce a mobile application to assist visually impaired persons in identifying Indian currency notes.

The central bank has invited bids from technology firms to develop the app.

"The application should be able to identify the denomination of legal tender banknotes of Mahatma Gandhi Series and Mahatma Gandhi (New) series by capturing the image of the notes placed in front of a mobile camera or scrolled across it," said the request for proposal issued by the RBI.

The application should be searchable via voice option in all app stores, the apex bank added.

Currently, banknotes in the denominations of Rs 1, Rs 10, 20, 50, 100, 200, 500 and 2,000 are in circulation in the country.
